Title (EN) SOLID DETERGENT BLOCK
(FR) BLOC DETERGENT SOLIDE
Abstract:
(EN) A solid detergent composition suitable for use in an industrial warewashing process and in the form of a block of compressed granular material is provided, said block having a weight of 0.2-10 kg and comprising: 25 - 35 % by weight of an alkalimetal hydroxide selected from sodium- and potassium hydroxide; 40 - 55 % by weight of a phosphate builder; 1 - 3 % by weight of a compressing aid selected from low foaming nonionic surfactants, metal soaps, paraffins, talcum powder, polyethylene glycol, sodium benzoate, mixtures of long chain ketones having more than 25 carbon atoms and fatty alcohols, and mixtures thereof; and up to 6% by weight of free water. Said block has optimal quality characteristics.
(FR) On décrit une composition détergente solide, apte à être utilisée dans un procédé industriel de lavage d'ustensiles et de vaisselle, et se présentant sous la forme d'un bloc de matériel granulaire comprimée, lequel bloc possède un poids compris entre 0,2 et 10 kg et comprend: 25 à 35 % en poids d'un hydroxyde de métal alcalin choisi entre l'hydroxyde de sodium et de potassium, 40 à 55 % en poids d'un adjuvant à base de phosphate, 1 à 3 % en poids d'un agent de compression choisi parmi des tensioactifs non ioniques et faiblement moussants, des savons métalliques, des paraffines, de la poudre de talc, du polyéthylèneglycol, du benzoate de sodium, des mélanges de cétones à chaîne longue comportant plus de 25 atomes de carbone et des alcools gras, ainsi que des mélanges de ces substances, et jusqu'à 6 % en poids d'eau libre. Ce bloc possède des caractéristiques qualitatives optimales.
